QCD color superconductivity in compact stars: color-flavor locked quark star candidate for the gravitational-wave signal GW190814
Zacharias Roupas, Grigoris Panotopoulos, Ilidio Lopes
At sufficiently high densities and low temperatures matter is expected to behave as a degenerate Fermi gas of quarks forming Cooper pairs, namely a color superconductor, as was ori…
Ejection of supermassive black holes and implications for merger rates in fuzzy dark matter haloes
Amr El-Zant, Zacharias Roupas, Joseph Silk
Fuzzy dark matter (FDM) consisting of ultra-light axions has been invoked to alleviate galactic-scale problems in the cold dark matter scenario. FDM fluctuations, created via the s…
Relativistic Gravitational Collapse by Thermal Mass
Zacharias Roupas
Gravity and thermal energy are universal phenomena which compete over the stabilization of astrophysical systems. The former induces an inward pressure driving collapse and the lat…
Secondary component of gravitational-wave signal GW190814 as an anisotropic neutron star
Zacharias Roupas
The gravitational-wave signal GW190814 involves a compact object with mass within the so-called low mass gap. As yet, a general consensus on its nature,…
Anisotropic Neutron Stars Modelling: Constraints in Krori-Barua Spacetime
Zacharias Roupas, Gamal G. L. Nashed
Dense nuclear matter is expected to be anisotropic due to effects such as solidification, superfluidity, strong magnetic fields, hyperons, pion-condesation. Therefore an anisotropi…
Gravitational Brownian motion as inhomogeneous diffusion: black hole populations in globular clusters
Zacharias Roupas
Recent theoretical and numerical developments supported by observational evidence strongly suggest that many globular clusters host a black hole (BH) population in their centers. T…
